You are buying a challenge coin, Ipswich Police Natural Resources Unit. This is an ERROR coin. The word "Resources" is misspelled on the front. Please see photo for details. 2.25 inches in width.
I have several challenge coins up for auction so please check them out at my ebay store. None of these coins were personally given to me. I buy/sell a lot of coins so I do not keep track of where any particular coin came from. I buy coins from a variety of sources (personal collections, estate sales, wholesalers, etc.).
